Patent GB-582557-A (GB)
Title: Improvements in the fractionation of glyceride oils
Filed: 1944-06-07
Abstract: Oils of the drying and semi-drying type are fractionated into a fraction more saturated and another fraction more unsaturated than the original oil by mixing the oil with an organic solvent, rapidly chilling the mixture so as to precipitate the more saturated fraction in a flowable form and separating the precipitate in a continuous centrifuge.  The precipitate is preferably in an amorphous or very fine crystalline form capable of flowing through the centrifuge for continuous separation as opposed to the ordinary crystalline form separable by filtration which packs or interlocks in the ordinary batch centrifuge. Non-polar solvents are preferred such as petroleum ether, hexane, trichlorethylene and any other hydrocarbons or chlorinated hydrocarbons; polar solvents such as acetone or furfural are less preferred in view of their tendency to produce ordinary crystals but they may be used if the conditions are controlled particularly as to the rate of chilling and the proper degree of agitation so as to minimise crystal formation.  In general, 1 part of oil to 1-20 parts of solvent is used.  The oil solvent mixture is agitated during the chilling operation, the oil being chilled to a temperature of -20 DEG F. to -60 DEG F.  The solvents may be recovered from each of the fractions obtained.  The process is particularly adapted for soya bean oil, linseed oil, fish oils, and less usefully for cottonseed oil, the so-called reversion factor of these oils associated with certain odour and taste characteristics being retained in the more unsaturated fraction where it is not objectionable in paints &c.  The more saturated fraction is adaptable for edible purposes &c.  Specifications 402,651 and 439,128 are referred to.

Title: Improvements in or relating to coverings for floors, walls and the like
IPC: D06N7/00
Filed: 1931-04-14
Abstract: In a method of manufacturing a covering for floors, walls, &c., tesser  of non-plastic material are assembled adjacent one another on plastic raw rubber or other vulcanizable material, and pressed into the latter so as to force it to flow between the edges of adjacent tesser , the vulcanizable material being then vulcanized, cured or matured so as to secure the tesser  together.  The rubber or other material may be carried on the backs of the individual tesser  before the latter are assembled. The tesser  may be made of vulcanized rubber, cured linoleum, wood veneer, stone, or earthenware.  When tesser  of wood veneer are to be used, a sheet of veneer is pressed on to a sheet of raw rubber in a cold press.  The combined sheet is then cut up to form tesser , for instance by means of dies.  The tesser  are then assembled to form a pattern, and pressed and vulcanized in a vulcanizing press.  A polish may be imparted to the wood surface by coating it with wax before pressing.  In place of raw rubber, synthetic rubber, rubber substitute, glue rendered insoluble in water, or uncured linoleum may be used, and instead of sheet rubber, rubber solution may be applied to the wood.  The assembled sheet is preferably afterwards mounted on a canvas or felt backing.

Abstract: 803,714. Gas-blast switches. BROWN, BOVERI & CIE. A.G. April 16, 1956 [April 14, 1955], No. 11537/56. Class 38 (5). The main contacts 1 of an air-blast circuitbreaker are bridged by a resistance 5 with an air-blast series interrupter 4, 10. A magnetic core 6 around the main conductor 3 attracts an armature 7 on a lever 8 which acts, with a spring 9, on a piston contact 10 so that under heavy current conditions the contacts 4, 10 cannot separate although the air pressure is applied to the underside of the piston contact. When the circuit of the main interrupter is broken, the armature 7 is released and contacts 4, 10 are opened by the compressed air which escapes via holes 12. The resistance does not remain in circuit for the interruption of normal load currents since the contacts 4, 10 are not held closed. In Fig. 2, movement of the piston 10 is blocked by a spring latch 15 which is held by a linkage 13, 14, while the armature 7 is attracted. Alternatively the linkage may be acted upon by a series current loop having movable limbs (not shown).

Abstract: Butadiene is separated from hydrocarbon mixtures also containing alkyl acetylenes by contacting with a basic cuprous salt solution, separating unabsorbed hydrocarbons, and subjecting the solution to successively higher temperatures to fractionally release butadiene and alkyl acetylenes separately in substantially pure form.  A C4 cut is extracted at 0-70, preferably 20-40 DEG  F., with a basic cuprous solution such as ammoniacal cuprous acetate containing per litre 3 gram ions cuprous ions, 4 gram ions acetate, and 11 gram mols. total ammonia, although amines such as methyl, dimethyl, or ethyl amines, and pyridine may replace ammonia.  The solution containing butadiene, acetylenes and other absorbed gases such as butenes and allenes passes down a stripper at 40-100 DEG , preferably 60-70 DEG  F., in counter-current to recycled butadiene, any butene which is freed being returned to the extractor.  The solution then flows to a desorber, being circulated in the base thereof through a reboiler to give a temperature of 120-180 DEG , preferably 140-150 DEG  F., in the bottom of the tower and 70-80 DEG  F. at the top.  Butadiene which may contain ammonia is recovered, part being recycled to the butene stripper.  The cuprous solution, still containing acetylenes and allenes, is fed from the base of the desorber to the top of a second similar desorber maintained at 160-230 DEG , preferably 180-200 DEG  F., by the reboiler.  The recovered gases are washed free from ammonia and may be separated by fractionation.  The cuprous solution is ammoniated and recycled to the extractor.  The pressure throughout the system may be 0-25 lbs./sq. in.  Figures are given to illustrate the variation of butadiene and ethyl acetylene partial pressures of a cuprous salt solution at various concentrations and temperatures.
